The end of the neck 25 In the referred embodiment 0f my lIWeIlis adapted to fit between the horizontal por- 85 tion, as ilustrated, 4 designates a conveyer tion 28 and the sleeve 24, and said neck 25 cylinder which is su-itably rigidly mounted is keyed to the horizont-a1 portion 28 by upon a supporting block 5, arran ed upon a means of the keys 29. The cylindrical Supporting plate 6. The Supportlng blOCl 5 sleeve 24 is thus rotatable in connection with iS adapted to be vertically adjusted by means the neck 25 and is rotatably mounted upon 90 ofthe screw-threaded bolts 7 which extend the Cylinder 23. Within the sleeve 24 advertically through the supporting plate 6. jacent its rear end, is l'arranged a splder 30, The supporting plate 6 is provided near'its Which'issplined to the rear end of the conre'ar end adjacent its opposite sides' with Voyer Shaft. 17,' upon which 1s suitably seboltS 8, which Securely hold Athe Supporting cured a spiral conveyer 31. This spider 30 95 40 plate 6 t0 tS foundation. At the forward is rigidly secured to'the sleeve. 24 by any end ofthe supporting plate 6, there is arsuitable means. i ranged an angle bracket comprising horlzon- I will now proceed to explain the manner tal and vertical sides 9 and 10 respectively. in which the cylinders 23 and 4 are cona The horizontal Side 9 issecured tothe Supnected. The cylinder 23 is provided at its 100 porting 4plate 6 by means of suitable `bolts forward end with a plurality of lon itudias illustrated at 11. Horizontally disposed nally disposed slots 32 which exten rearbolts 12 are screw-threaded through the ver-Y' wardly and communicate with slots 33, tical side 10 and are adapted to engage the which are arranged at right angles to the supporting block 5 for preventing thelonglslots 32. Arranged` at the junction of the 105 tudinalgdisplacement of the same. The concylinders 4 and 23 is a cylindrical collar 34, veyer cylinder. 4 hasV its forward end closed which has its forward end provided with a by means of a head 13, which is secured to peripheral flange 35. The collar 34 1s prosaid cylinder .by means of bolts 14.` The vided `near its rear end with a pluralltybf headl is provided centrally thereofwith a pins 36 which are adapted to reglster wlth 110 cylindrical opening 15 within which 1s `arthe slots 32, and be introduced into the slots ranged a cylindrical 4tubular bearing 16, 33 by means of a longitudinal movement of of pins 43 which said pins through the slots 32. By this construction it is obvious that the pins 36 may be arran ed within one end of the slots 3 3, by slight y rotating the sleeve 34 after sald pins have been introduced within said slots 33, and that the pins 36 will thus be prevented from being withdrawn through the slots 32. After the pins 36 have been arranged at one end of thed slots 33 and the collar 34 accordingly locked to the cylinder 23, I prevent further rotation 'of' the collar 34 by keying the same to the cylinder 4, as shown at 37. Arranged upon the collar 34 and in engagement with the flange 35 there- 0f, is a circular ring 38 provided upon its rear end with a cut out port-ion 39. The flange 35 of collar 34 is provided with a plurality of .pins 40, which register wlth and are adapted to be inserted within openings4 41 formed upon the forward end of the ring 38. The ring 38 is thus non-rotatable with relation to the collar 34 and the conveyer cylinder 4. Arranged within the cut out portion 39 of the ring 38, is a bearing ring 42 which engages the forward end of the sleeve 24. The vertical portion 27 of the sleeve 24 is provided with a plurality extend within openings 44 formed upon the rear end of the ring 42. 4The ring 42 is thus caused to rotate with the sleeve 24. An oil cup 45 is arranged upon the ring 38 and 'communicates the engaging surfaces of the ring 42 and ring 38, by means of a channel 46.

From the construction above described, it is to be understood .that Vwhen the vkey 37 is removed, the collar 34 may be rotated so that the pins 36 may be.withdrawn 'through the slots 32, whereby the cylinders 23 and 4 are disconnected. Itis to be further understood, that the flange 35 may be withdrawn from the ring 38 and the ring 42 may be `moved forwardly away from the sleeve 24. It` is to be understood that the greatest amount of wear caused by frictional engagement ofthe parts of the device will naturally fall upon `the cylinder 23 and the bearing ring 42.- It is obvious by the above Adescribed construction that the cylinder 23 and ring renewed derstood 42 may be readily removed and when necessary. It is to be unthat Athe bearing ring 42 may be formed in two parts, which will expedite the removal of the same.

At the forward end of the conveyer cyl- .inder 4, and upon the upper side thereof,

islformed a chute 47, which communicates with the conveyer cylinder by means of the The upper end of the chute 47 1s flanged as at 49, for the purpose of receiving thereupon the lower flanged end 50 of a hopper 51, the flanges 49 and 50 being `secured together by means of suitable bolts The upper end of the hopper 51 is pro\ vided with the outwardly extending flange with rotatable pin 75, said 53, upon which is arranged the base 54 of a feed chute 55, provided upon its upper end with an outwardly spreading mouth 56. The base 54 is secured upon the flange 53 by means of bolts 57. O posite sides of the feed chute 55 are rovidled with alined vertical slots 58, Wit in which are arranged screw-threaded projections 59 formed upon an adjustable guard 60, and the projectlons 59 are provided with nuts v61, whereby the guard 60 may be clamped in its adjusted position. The flanges 49 and 5() of the chute 47 and hopper 51 respectively, are extended upon opposite sides of the chute to form a ined sleeves'62, within which are arranged bearings 63, through which is journaled a shaft 64, which is arranged parallel with the conveyer cylinder 4. The shaft 64 is provided with rings 65 lixedly secured thereto which prevent the longitudinal displacement `of the shaft, and the shaft- 64 is further provided with a fixed rotary feed valve 66, which is dis osed within the ho per 51 and chute 47. ear the forward endlbf the shaft 64 is arranged the ratchet Wheel 67, which is rigidly mounted thereon, and which is engaged by a pawl 68 pivotally mounted upon one arm of a bell-crank lever 69. The bellcrank lever 69 is loosely mounted upon the shaft 64, and has pivotally connected to its lower arm an actuating rod 70. Rotatabl mounted upon the forward end of the sha t -17, is a crank 71, provided With-a longitudinal slot 7 2. The crank 71 is prevente from having longitudinal movement upon the shaft 17 by means of a pin 73 which extends through a portion of said 'crank and has its inner end arranged Within a groove 74 upon the shaft 17. The

actuating rod has its lower end provided with a with a rigid collar 76. The `p1n 75 is extended beyond the collar 76 and is arranged within the slot 72. The pin 75 may be thus adjusted longitudinally of the crank 71, and

peripheral 105 I pin 75 being provided said pin 75 is provided with a nut 77 for clamping the same in a upon the crank 71.

The numeral 78 designates a clutch splined upon the conveyer shaft 17 and provided with a clutch face, for coperation with a clutch face 80 formed upon the crank 7l. The clutch 78 is urgedL into engagement Withthe crank 71, by means of a coil spring 8l, which surrounds the shaft 17 and is compressedb`etween the ring 19 and clutch 78. The 'head 13 of the conveyer cylinder 4 is provided with a forwardly. extending support provided with a bifurcated free end .82, upon which is pivotally mounted a shifting lever 83, by means of a pin 84. The inner end of the shifting lever 83 has formed thereon a curved section 85, which is adapted to be arranged within a circumferential groove 86 formed upon the clutch 7 8. It is desired position in a desired position by means of a latch device 85.

Briefly the operation f the device is as follows s--Material being fedinto the hopper 51, the .same is conducted by the rotary feed valve 66 to the conveyer cylinder 4. The material is then carried by the conveyer 31 to the tube mill 26, which rotates the conveyer 31 and which is in turn rotated by a driving 'pinion 86a which is keyedy upon a shaft 87, and arranged to mesh with aring 88 provided with teeth 89. It is obvious thatvthe feed valve 66 is rotated intermittently and that such rotation may be regulated by adjusting the pin 75 in the slot 72 as above described. i

I have found that itis advantageous `to have the spiral conveyer illustrated in Fig; 1 rotate-d at a greater rate of speed than the reduced neck 25 by which said conveyer is rotated. To accomplish thisresult, I employ the arrangement of elements illust-rated in Fig. 4. In the form of my invention illustrated in Fig. 4, the shaft 17a is keyed in the same manner to the spider bearing 30 which is rigidly connected to the sleeve 24 as above described. lThe shaft 17EL extends through an openingl in the head 13, and the shaft 17a is provided upon its forward end with a rigidly mounted pinion 90. In this form of my invention the spiral conveyer blade 31 is lrigidly secured to a tubular sleeve 91, which is rotatably mounted upon the shaft 17 and journaled through the head 13. The tubular sleeve 91 terminates adjacent the pinion 90 and is provided at its forward end with a fixed pinion 9,2. -By reference'to Fig. 4 it is `obvious that the pinion 92 is smaller than the pinion 90, for a purpose to be hereinafter apparent.

In the modified form of my invention as shown in 4,4;he head 13 is provided with an extension 93 upon the upper side of which is formed an upstanding arm 94'which is spaced away from the head 13. The head '13 is further provided upon itsy periphery withan upstanding section 95V to which is rigidly connected an angular bracket 96. A shaft 97 is provided with an enlarged screwthreaded end 98 which is arranged within an opening formed upon the arm 94, and the enlarged screw-threaded end 98 is locked upon the said arm 94 by means of nuts 98. The shaft 97 extends through an opening formed upon the vertical portion of the support 96, and the shaft 97 is parallelk with the shaft 17, and said shaft 97 carries a cylindrical sleeve 99 which is rotatably` mounted thereon. The sleeve 99 has formed integral therewith a small and larger pinionl` mounted Aupon theshaft 97 and meshed with the large and smaller pinions 90 and 92 respectively. The cylindrical sleeve 99 is journaled through the opening in the vertical portion of the angular support 96, as illustrated in Fig. 4. rlhe clutch 78, which in- Fig., 1 is keyed upon the shaft 17, is in Fig. 4, keyed upon the sleeve 99 and is designated by the numeral 102. The clutch 102 is adapted to engage a crank 103 vrotatably mounted upon the sleeve 99 and which corresponds to the crank 71, shown in Fig. i1. The connecting rod is connected to the crank 103 in the same manner as it is connected` to crank 71 and therefore need not be explained again. y l

' In the operation of the modified form of my' invention, the shaft 17a is rotated at the same rate-of lspeed asreduced neck 25, and the rotation of the shaft 17 a is imparted to the pinion 90. Thev pinion 90 rotates the smaller pinion 100 which accordingly rotates the sleeve 99 and the pinion 101. It is obvious that. the lrotation of theipinion 101 will be faster than the rotation of the pinion 90. The pinion 101 then rotates a smaller pinion 92 which in lturn operates the spiral conveyer'. It is thus obvious that the conveyer derives its rotation from4 the reduced neck 25 andthat said conveyer is rotated at a higherv rate of speed than said y neck 25. It is to be understood -that the feed valve 66 is actuated by the connecting rod 70 i sa-idfconveyer cylinder, Said second cylinder extending within said reduced neck, and a 'conveyer arranged within said cylinders.

2. In a device of the character described, `the combination with a rotatable mill casing provided with a reduced extension, of a stationary conveyer cylinder forA coperation therewith, a cylinder arranged in engagemerit with and in end to end relation to said conveyer cylinder, a collar for tretaining said cylinders in registration, said second named cylinder being arranged within said reduced extension, a conveyer arranged within said cylinders, means for imparting rotation from said reduced extension to s'aid conveyer, and means for locking said collar 'to said second named cylinder. l
